CROSS-BAR FOR VEHlCLE-SHAFTS.

SPECIFICATION formingpart of Letters Patent No. 704,460, datedJuly 8,1902.

Application filed December 26, 1901. Serial No. 87,308. (No model.)

To all whom it may concern.-

Be it known that we, SAMUEL H. HAYDEN and HARLOW D. HATHAl/VAY, citizensof the United States, residing at Flint, in the county of Genesee andState of Michigan, have invented new and useful Improvements inCross-Bars for Vehicle-Shafts, of which the following is aspecification.

Our invention relates to cross-bars for connecting vehicle-shafts; andthe object of the same isto construct a metal bar of this descriptionwhich shall be strong, light, and durable.

The novel construction used by us in carrying out our invention is fullydescribed in this specification and claimed, and illustrated in theaccompanying drawings, forming a part thereof, in which- Figure 1 is aperspective of our cross-bar and fragments of the shafts. Fig. 2 isalongitudinal section of our bar. Fig. 3 is a transverse section of thesame on the line 3 3, Fig. 2. Fig. 4; is a detail of one end of the bar.Fig. 5 is a detail of the same inverted. Fig. 6 is a detail of afragment of the bar, showing the method of strengthening the same.

Like numerals of reference designate like parts in the diiferent viewsof the drawings.

The numeral 1 designates the body of our bar, which is formed ofheavymetal and is U-shaped in cross-section. The sides 2 are thickest in themiddle and are rounded off on the lower edge at 3. A whiffietree-plateis mounted centrally the body and comprises a circular disk 4, having acentral boss 5 and a circular flange 6. An apertured cylinder 7, havingoppositely-extending ribs 8 thereon, is mounted intermediate the sidesof the bar with its aperture in line with the aperture in the boss, andthereby serves as a guide for the bolt for securing the whiflietree tohold the whiftletree from wabbling. The body 1 is closed at the ends at0.

To serve to secure the bar to shafts. oppositely-extending vertical bars10 are formed on the ends ofthe body 1, on each side thereof, horizontalears 11 are formed on the top, and a horizontal strap or shaft-iron 12is attached to the bottom. Apertures 13 are formed in the ears 10 and 11and the strap 13 and serve to accommodate bolts 14 for securing the barto the shaft 15. The strap 12 is reinforced on the bottom by ribs 16 and17.

The shafts are attached to the vehicle by means of curved shaft-irons18, secured by bolts 19 to the ends of the shafts and the under sides ofthe straps 12.

In operation the bar is bolted to the shafts 15, which fit between theear 11 and strap 12 and abutting the ears 10. It is evident from theconstruction of our bar that far greater strength is secured for theamount of material used than in the solid bar.

Having thus described our invention, what we claim as new, and wish tosecure by Letters Patent, is-

In a cross-bar for vehicles, the combination of a hollow body U-shapedin cross-section, a Whifiietree-plate mounted centrally said bar,apertured ears and a strap mounted on the ends of said body to serve insecuring said bar to shafts.

In testimony whereof we have hereunto set our hands in presence of twosubscribing wit nesses.
